Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517462, here are decompositions:

73 + 31517389 = 31517462
313 + 31517149 = 31517462
643 + 31516819 = 31517462
673 + 31516789 = 31517462
709 + 31516753 = 31517462
733 + 31516729 = 31517462
829 + 31516633 = 31517462
859 + 31516603 = 31517462

Showing the first eight; more decompositions exist.
